The Coherent Wave phasing plug
structure has four equal length passages to provide in-phase summation
of diaphragm output at the 38 mm
exit, This optimized configuration
produces coherent acoustical power
up to much higher frequencies than
more conventional designs.
The diaphragm design includes JBL's
exclusive three-dimensional diamond
pattern surround' tuned to reduce
fatigue inducing stresses in the membrane and support structure. This
provides predictable normal resonance modes, and radial reinforcing
ribs increase diaphragm stiffness. This
diaphragm design combined with the
Coherent Wave phasing plug
increases the 2451's output in the 5
kHz to 20 kHz range.

High temperature voice coil former materials and adhesives enable the 2451H/J to handle higher power levels
over extended periods of time. The voice coils themselves
are identical to previous JBL models, so that impedance
and network matching will be the same. After manufacture,
the frequency response of each transducer is tested for
conformity to JBL's rigid performance standards.

The model 2451H/J is ruggedly constructed to withstand
the rigors of both fixed installations and touring applications. All tolerances are held to the same high levels traditionally associated with JBL designs. The JBL manufacturing
process permits the use of rim centered diaphragms for
instant interchangeability and ease of field service.
